Shrewsbury could be climbing out of the League One relegation zone. As things stand they would go up to the heady heights of 19th from 23rd thanks to their 1-0 lead over fellow strugglers Bristol Rovers.

The Shrews would also go above Gillingham, Oxford and Bradford, who are all losing.

Meanwhile, Rotherham and Wigan have just kicked off their second half.

Danny Fox's head injury forced seven minutes of first-half stoppage time.

While we wait for the second halves to start up and down the country, some thoughts from the managers following the 1-1 draw between Boro and Leeds.

Middlesbrough manager Tony Pulis told BBC Tees:

"In the first half we were the better team and our midfield players were fabulous. When we were attacking, we were having five or six players in the box and around that area, which was fantastic.

"We tired a bit in the second half, Leeds came into it as the game went on, and we certainly didn't need to concede a goal from a set-play - something that's really disappointed me."

Leeds head coach Marcelo Bielsa told BBC Radio Leeds:

"We could have won the game. We had 15 minutes in the first half where we were not at ease, but apart from that segment we dominated the game, we created chances, we deserved to score the goal and probably deserved to score other goals."
